One of the Channel Islands (8)
I believe the answer is:
guernsey
'one of the channel islands' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for guernsey that I've seen before include "Neighbour of Jersey" , "Second largest of Channel Islands" , "Lyric poem" , "Second-largest Channel Island" , "Sir Walter Scott novel" .)
